Abstract: From the viewpoint of lithofacies and paleogeography this paper describes the geological developmental history of North China Basin,where in middle-late Proterozoic Era it was a paleo-land with sediments of aulacogens developed in its north and south margins. In Paleozoic Era stable marine sediments of platform type covered it. And in Meso-Cenozoic Era continental fault-depressional basin sediments well developed. According to its petroleum generation and accumulation regularities, six propect areas for oil and gas exploration are pointed out:(1) Oil and gas pools of "Cenozoic source and pre-Mesozoic reservoir" type represented by Renqiu paleo-buried hill;(2)Tertiary complex petroleum accumulation belts of "self-souce and self-reservoir" type;(3)Middle and Upper Proterozoic original oil and gas pools in Yanshan aulacogen;(4)0i1 and gas pools of "Paleozoic source and paleozoic reservoir" type represented by well Konggu-3 and Konggu-7;(5)Oil pools of "Paleozoic source and Mesozoic/Cenozoic reservoir" type represented by well Konggu-4;(6)Mesozoic coalbearing formation of lacustrine facies,which is still a new prospect field for oil and gas exploration although it was seriously deformed during its evolution and is now in tatters.

摘要： 文中以岩相古地理的观点论述了华北盆地的地质发展历史,即中晚元古代为古陆区,南北边缘地带发育拗拉槽型沉积;古生代为稳定的海相地台类型沉积;中新生代为陆相断-坳陷盆地沉积。指出华北盆地成烃、成藏的规律以及勘探油气的6个领域:一是以任丘古潜山为代表的“新生古储”油气藏;二是第三系“自生自储”复式油气聚集带;三是中、上元古界燕山拗拉槽原生油气藏领域;四是以孔古3井、7井油藏为代表的“古生古储”油气藏;五是以孔古4井油藏为代表的“古生中储”’或“古生新储”型油藏;六是中生界湖相沉积含煤地层烃源岩,虽改造剧烈,残留体肢离破碎,但仍是一个找油的新领域。
